The GFW of Comcast?

There have been a number of recent reports stating that Comcast is interfering with file-sharing traffic including BitTorent, Gnutella, and Lotus Notes. The reports state that the technique used is the TCP RST packet technique that the GFW of China has made (in)famous. (An intermediary send RST packets to both ends of a connection, effectively terminating it. For more technical info see Ignoring the Great Firewall and ConceptDoppler.)
